Detection of CAG repeats in pre-eclampsia/eclampsia using the repeat expansion detection method

Abstract

Pre-eclampsia/eclampsia is a serious disorder of human pregnancy that has a worldwide incidence of 2-10% and carries a severe morbidity and mortality risk for both mother and child. Its precise cause remains unknown. However, there is increasing evidence of an underlying complex maternal genetic susceptibility. Its high population incidence in the face of strong negative selection pressure suggests that the gene(s) involved have a selective advantage and/or a high mutation rate. One class of genetic diseases that involve a high mutation rate are the trinucleotide repeat expansion diseases. Thus, the aim of this study was to determine whether there is an association between a trinucleotide (C..
